Scraped-Surface Heat Exchanger – Vertical Type

This heat exchanger is designed for the hygienic heating and cooling of food or personal-care products with high viscosity, stickiness or granular texture. It is suitable for low- to medium-viscosity products such as chocolate, ketchup, soups, sauces, fruit purées, baby food, desserts, body lotions, face creams and shampoos. Product pumped through the cylinder is turbulated at the system’s surface by the rotor and blades, achieving heat exchange.

For optimum heat transfer, the unit has two matching heat transfer surfaces; continuous scraping across the entire surface ensures efficient heat transfer. General functions include: heating and cooling of flowable products that form a film layer on the heat transfer surfaces, the crystallization process, and processing of particulate products with different physical/chemical properties.

It can be manufactured in different configurations and materials to meet the specific requirements of the product being processed. The standard Interm-type unit consists of a heat exchanger cylinder with a 152 mm inner diameter and a heat transfer surface of 0.28 m². On all models, product-contact surfaces are 316L stainless steel. It can operate at temperatures between -34.4°C and 149.0°C.
